Section 3(2) of the Advocates Act, 1961, specifies the composition of a State Bar Council. The number of members depends on the number of advocates on the state's electoral roll:
If the electorate is 5,000 or less, the number of members is 15.
If the electorate is between 5,000 and 10,000, the number of members is 20.
If the electorate exceeds 10,000, the number of members is 25.
Since the question asks for the maximum limit, and most states have more than 10,000 advocates, the maximum possible number of members is 25.
